How to force Chrome not to turn down the volume?

Question

Google Chrome

I have 2 monitors: the main monitor is running Chrome as normal and the second monitor has another chrome window running with options

--allow-file-access-from-files --disable-web-security --app=http://127.0.0.1:2708/

When a window on the second monitor launches an application using getUserMedia (microphone and camera), then the sound from the adjacent window (on the main monitor) is reduced almost to the very limit.
I would like to somehow fix this matter: D
The application code that launches all this happiness:

window.onload = function(){
  var videoPlace = document.getElementById('video');
  var videoStreamUrl;
  navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia || navigator.msGetUserMedia;
  window.URL.createObjectURL = window.URL.createObjectURL || window.URL.webkitCreateObjectURL || window.URL.mozCreateObjectURL || window.URL.msCreateObjectURL;
  navigator.getUserMedia({video:true,audio:true},function(stream){
    videoStreamUrl = window.URL.createObjectURL(stream);
    videoPlace.src = videoStreamUrl;
  },function(){
    console.log('...');
  });
};

In general, my problem was solved quite simply:
1. Open the properties of the Microphone. In the "Advanced" tab, uncheck the "Give exclusive mode priority" checkbox.
2. In the "Listen" tab, the "Listen to this device" checkbox should not be checked.
3. In the "Management of sound devices" (Sound) in the "Communication" tab, select "no action required".
Chrome no longer encroaches on the volume between its windows :)
